So my son is almost 6 months old and is teething and in the last two weeks has cut two bottom teeth he is now refusing to nurse i only was nursing at night because of being back at work but now he wont at all and now that i am only pumping it seems like my milk suppy isnt as good and i almost cant keep up with him. I was pumping anywhere from 6-10oz a sitting and now maybe 4-6oz I am pumping every 3-4 hours do I maybe need a different pump with higher suction or a double pump or is that normal?????? I am using the Avent brand electric/manual single pump now any help would be appreciated Thank you!!
